Answer:
the change in the system internal energy is 20 J
Explanation:
The computation of the change in the system internal energy is as follows:
Since the volume remains constant so the work done would be zero
Now the change in the internal energy is
= Heat given to system - work done
= 20 J - 0
= 20 J
hence, the change in the system internal energy is 20 J
The same is to be considered
Simplified formula
Let's count atoms of all

Answer:
The answer to your question is below
Explanation:
Ions are atoms that are electrically charged. There are two kinds of ions
- Cations are ions with a positive charge.
- Anions are ions with a negative charge.
Sodium forms cations because it loses one electron and I can bound to anions like halogens.
Then, the paragraph will be:
"If the sodium ion has a + charge after ionization, then it will interact with a Chlorine ion which has a - charge".
Answer:
C A B
Explanation:
come on, you also know this from normal water waves.
which ones are stronger (= have more energy) ? the small ones or the big ones ?
and the same applies to all waves. the bigger the waves (higher amplitude), the more energy.
